Description

[Technical field]

[0001] The present invention relates to a sample collection container. [Background technology]

[0002] When testing feces and other samples excreted from animals, including humans, it is desirable to quantitatively collect the samples and store and transport them hygienically. For example, Patent Document 1 describes a stool collector as a sample collection container. This stool collector comprises a stool collection stick and a container body. The stool collection stick has a gripping portion on one side and a stick portion on the other side. A stool collection portion is provided at the tip of the stick portion. The stool collection portion is composed of a through hole, a groove portion, etc. This stool collection portion is configured to be able to collect about 0.2 mg to 0.8 mg of stool. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5424416 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in some cases, a quantified and larger amount of sample (for example, about 20 to 50 times) is required for testing. However, with the configuration of the stool sampler as in Patent Document 1, it is difficult to accommodate a large amount of sample. [Means for solving the problem]

[0005] A sample collection container for solving the above problem includes a container body including a container opening formed on one side, a storage section for storing a sample inserted from the container opening as a stored sample, an outlet for discharging a part of the stored sample as an extrusion sample, and a container seal for closing the outlet, and a lid for closing the container opening, the lid including an insertion port through which an extrusion member for pushing out the extrusion sample from the outlet is inserted, and a lid seal for closing the insertion port. Either the container body or the lid includes a tubular portion for storing a part of the stored sample as the extrusion sample. The tubular portion is configured such that the extrusion member inserted from the insertion port is inserted, and the extrusion sample is discharged from the outlet.

[0006] According to the above configuration, after the sample is contained in the container body, the container opening of the container body is closed with the lid. At this time, an extruded sample, which is a part of the contained sample, is contained in the cylindrical portion. The contained sample is transported or the like while contained in the sampling container. When the contained sample is to be removed, an extrusion member is inserted into the cylindrical portion through the insertion port. Then, the extrusion member discharges the extruded sample in the cylindrical portion from the discharge port. Therefore, the extruded sample is quantified by being contained in the cylindrical portion.

[0007] In the above-mentioned sample collection container, the tubular portion may be provided with the lid, and the container body may be configured to have a guide rib provided on the bottom wall and with the outlet located inside. According to the above-mentioned configuration, when the container opening is closed with the lid, the tubular portion is guided by the guide rib, so that the tip can be smoothly brought close to the outlet.

[0008] In the above-mentioned sample collection container, the container body may have an outer rib erected on the bottom wall, and the outer rib may be configured to be outboard of and taller than the guide rib. According to the above-mentioned configuration, since the outer rib is taller than the guide rib, the contained sample is naturally drawn to the inside of the guide rib, and the amount of contained sample increases in that area. Therefore, the extrusion sample contained in the cylindrical portion during the process of closing the container opening with the lid body is contained without any gaps within the cylindrical portion. As a result, a quantified amount of the extrusion sample can be discharged from the discharge port.

[0009] In the above-mentioned sample collection container, the cylindrical part may be configured to have a through-hole that connects the extrusion space formed in the cylindrical part to the space of the storage part. According to the above-mentioned configuration, when a part of the stored sample is separated from the other samples and stored as an extrusion sample in the cylindrical part during the process of closing the container opening with a lid body, the through-hole allows the air in the cylindrical part that is pushed out to flow to the outside. Therefore, the extrusion sample is stored in the cylindrical part without any gaps. As a result, a quantified amount of the extrusion sample can be discharged from the discharge port.

[0010] In the above-mentioned sample collection container, the container body may include the bottom wall and the peripheral wall, the lid may include a lid wall and a lid peripheral wall, and the height of the cylindrical part may be set so that the tip of the cylindrical part is spaced from the tip of the guide rib when the tip of the lid peripheral wall is in contact with the tip of the peripheral wall. According to the above-mentioned configuration, the tip of the lid peripheral wall and the tip of the peripheral wall are aligned with each other, and then the container opening can be closed with the lid. In other words, it is possible to prevent an erroneous operation of forcibly closing the container opening with the lid when the position of the tubular part and the guide rib are misaligned.

[0011] In the above-mentioned sample collection container, at least one end of the tip of the cylindrical portion and the tip of the guide rib may be configured to have a guide portion that guides the entry of the cylindrical portion into the inside of the guide rib. According to the above-mentioned configuration, by having at least one end of the tip of the cylindrical portion and the tip of the guide rib have a guide portion, the cylindrical portion can easily enter the inside of the guide rib when the container opening is closed with the lid.

[0012] In the above-mentioned sample collection container, the lid may be configured to be screwed to the container body by a screw action. According to the above-mentioned configuration, the container opening can be securely closed by screwing the lid to the container body by a screw action. This makes the sample collection container excellent in airtightness. Effect of the Invention

[0013] According to the present invention, more samples can be collected and quantified. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] A sampling container to which the present invention is applied will be described below with reference to the drawings. [Overall structure] As shown in Fig. 1 and Fig. 2, the sample collection container 1 is, for example, a stool collection container for animals. Specifically, the sample collection container 1 is a container for collecting feces as samples from industrial animals such as cows and pigs that are kept for livestock farming. The sample collection container 1 used for such purposes is a container that holds a larger amount of feces than a stool collection container for collecting and storing feces excreted from humans as clinical test samples. The sample collection container 1 can quantify the sample and discharge it.

[0016] The sample collection container 1 comprises a container body 10 and a lid body 30. Each of the container body 10 and the lid body 30 is a molded part made of synthetic resin such as polypropylene, polyethylene, polystyrene, ABS, acrylic resin, etc. The container body 10 has an outlet 11 at the center of the bottom surface. In this embodiment, the outlet 11 is circular. The outlet 11 is an opening through which the sample is discharged. The outlet 11 is closed by a container seal 12. The container seal 12 is made of, for example, a peel film. The container seal 12 is a pull tab that has a closing portion 12a larger than the outlet 11 and a tab 12b that serves as a knob.

[0017] The container seal 12 is a film based on a material such as aluminum, polyethylene terephthalate, polypropylene, or polyethylene, or a film made of a composite material thereof. The surface facing the inside of the container body 10 is the surface that comes into contact with the sample, and is therefore water-repellent coated. This film is attached to the outer surface of the bottom wall 13 of the container body by heat sealing. The container seal 12 may also be attached by an adhesive.

[0018] The lid body 30 has an insertion opening 31 at the center of the upper surface. In this embodiment, the insertion opening 31 is circular. The insertion opening 31 is an opening through which the extrusion member 2 is inserted. The insertion opening 31 is closed by a lid seal 32. The lid seal 32 is made of a pierceable film that can be easily torn by the extrusion member 2. The lid seal 32 is a film based on aluminum, polyethylene terephthalate, polyethylene, or a composite material film thereof. This film is attached to the lid body 30 by heat sealing. The lid seal 32 may also be attached by an adhesive.

[0019] [Container body] As shown in FIG. 3, the container body 10 is a cylindrical container with a bottom. The container body 10 includes a bottom wall 13 and a peripheral wall 14. The bottom wall 13 is a circular plate and forms a bottom surface. The bottom wall 13 has a discharge port 11 formed of a through hole in the center. The peripheral wall 14 is a cylindrical wall erected on the outer periphery of the bottom wall 13. In the container body 10, the tips of the peripheral walls 14 are aligned at the same height and form a circular container opening 15. In addition, the space surrounded by the bottom wall 13 and the peripheral wall 14 forms a storage section 16 that stores a sample and is continuous with the container opening 15. The outer peripheral surface of the peripheral wall 14 includes a flange 17. The outer peripheral surface of the peripheral wall 14, above the flange 17, includes a screw section 18 formed of a helical protrusion.

[0020] A guide rib 21 is provided around the discharge port 11 on the inner surface of the bottom wall 13. The guide rib 21 is an annular rib. The discharge port 11 is located on the bottom surface of the space surrounded by the guide rib 21. The tip of the guide rib 21 is located at a lower height than the tip of the peripheral wall 14. A cylindrical portion 36 of the lid body 30 is inserted into the space inside the guide rib 21. The inner surface of the guide rib 21, the tip portion, is provided with a container side guide portion 21a. The container side guide portion 21a is configured as an inclined surface. The inclined surface is configured so that the thickness becomes thinner toward the tip. As a result, the opening formed by the tip of the guide rib 21 is configured to have a larger diameter on the tip side than the bottom side due to the container side guide portion 21a, making it easier to insert the cylindrical portion 36.

[0021] On the inner surface of the bottom wall 13, an outer rib 22 is provided outside the guide rib 21. The outer rib 22 is spaced apart from the guide rib 21. The outer rib 22 is also spaced apart from the peripheral wall 14. The tip of the outer rib 22 is located between the tip of the peripheral wall 14 and the tip of the guide rib 21. The guide rib 21 is an inner rib with respect to the outer rib 22. The outer rib 22 is preferably a rib concentric with the outer rib 22.

[0022] As shown in FIG. 5, when the height of the peripheral wall 14 from the inner surface of the bottom wall 13 to the tip is (H1), the height of the guide rib 21 from the inner surface of the bottom wall 13 to the tip is (H2), and the height of the outer rib 22 from the inner surface of the bottom wall 13 to the tip is (H3), (H2)<(H3)<(H1) Therefore, in the storage section 16, when the tip of the peripheral wall 14, the tip of the outer rib 22, and the tip of the guide rib 21 are connected, the storage section 16 has a mortar shape with the deepest part being above the discharge port 11. Therefore, more sample is stored in the central part where the discharge port 11 is located.

[0023] [Cover body] As shown in FIG. 4, the lid body 30 includes a lid wall 33 and a lid peripheral wall 34. The lid wall 33 is a disk and forms the upper surface. The lid wall 33 has an insertion opening 31 formed of a through hole in the center. The lid wall 33 is a part that closes the container opening 15. The lid peripheral wall 34 is a cylindrical wall erected on the outer periphery of the lid wall 33. In the lid body 30, the tip of the lid peripheral wall 34 is aligned at the same height. The inner circumferential surface of the lid peripheral wall 34 has a screw shape 35 formed of a spiral uneven portion. The screw shape 35 corresponds to the screw portion 18. When the lid body 30 closes the container opening 15 and is fastened by a screw action, the tip of the lid peripheral wall 34 comes close to the flange 17. Also, when the lid body 30 closes the container opening 15 and is fastened by a screw action, the tip of the peripheral wall 14 comes close to the inner surface of the lid wall 33. The outer surface of the lid peripheral wall 34 is formed with unevenness 34a that acts as an anti-slip surface. The unevenness extends in the height direction of the peripheral wall 14 and is provided in the circumferential direction.

[0024] The lid body 30 is screwed into the container body 10 by a screw action at a number of rotations of about 2 to 3. The threaded portion 18 and the thread shape 35 are set so that the number of rotations is about 2 to 3 in order to suppress a decrease in the operability of rotating the lid body 30.

[0025] A tubular portion 36 is provided on the inner surface of the cover wall 33 around the insertion port 31. The tubular portion 36 has, for example, a cylindrical shape. The upper end of the tubular portion 36 is the insertion port 31, and the lower end is an outlet facing the discharge port 11. The inside of the tubular portion 36 is an extrusion space 37 in which a sample is filled. The sample in the extrusion space 37 is the extrusion sample, and is extruded from the discharge port 11 by the extrusion member 2.

[0026] The cylindrical portion 36 has a slit 38 as a through portion from the tip (lower end) to the base (upper end). The slits 38 have a linear shape, and are provided in multiple positions facing each other. In addition, multiple slits 38 are provided in parallel to each other in the circumferential direction. In the process of closing the container opening 15 with the lid body 30, a part of the contained sample is contained in the cylindrical portion 36 as an extrusion sample, separate from the other samples. At this time, the slits 38 push the air in the extrusion space 37 outward. As a result, the cylindrical portion 36 is sufficiently filled with the extrusion sample without any gaps. Then, the extrusion member 2 inserted from the insertion port 31 is inserted inside the cylindrical portion 36. The inner diameter (D3) of the cylindrical portion 36 is a dimension that allows the extrusion member 2 to be inserted, and is the same as, for example, the diameter (D4) of the discharge port 11 and the diameter (D5) of the insertion port 31 (see FIG. 5).

[0027] The outer surface of the cylindrical portion 36, the tip portion, is provided with a lid side guide portion 36a. The lid side guide portion 36a is configured as an inclined surface. The inclined surface is configured to taper so that the thickness becomes thinner toward the tip. As a result, the tip portion of the cylindrical portion 36 is tapered by the lid side guide portion 36a, so that it can be easily inserted into the inside of the guide rib 21.

[0028] The outer diameter (D1) of the cylindrical portion 36 is smaller than the inner diameter (D2) of the guide rib 21 ((D1)<(D2)). A gap 39 is formed between the outer peripheral surface of the cylindrical portion 36 and the inner peripheral surface of the guide rib 21. In the process of closing the container opening 15 with the lid 30, the cylindrical portion 36 is inserted inside the guide rib 21. At this time, the contained sample inside the guide rib 21 moves inside and outside the cylindrical portion 36 while being pushed by the tip of the cylindrical portion 36. The gap 39 becomes a passage through which the contained sample pushed by the tip of the cylindrical portion 36 moves to the base end side of the cylindrical portion 36 (see Figure 6).

[0029] The height (H4) from the inner surface of the cover wall 33 to the tip of the cylindrical portion 36 is such that when the cover 30 closes the container opening 15 and is tightened, it does not come into contact with the inner surface of the bottom wall 13, leaving a slight gap. This gap is continuous with the gap 39. In other words, when the height (H4) from the inner surface of the cover wall 33 to the tip of the cylindrical portion 36 is compared with the height (H1) of the peripheral wall 14 from the inner surface of the bottom wall 13, (H4)<(H1) It becomes.

[0030] In addition, when comparing the height (H4) from the inner surface of the cover wall 33 to the tip of the cylindrical portion 36 with the height (H1) of the peripheral wall 14 from the inner surface of the bottom wall 13, the height (H2) of the guide rib 21 from the inner surface of the bottom wall 13, and the height (H3) of the outer rib 22 from the inner surface of the bottom wall 13, (H2)<(H3)<(H4)<(H1) It becomes.

[0031] In addition, when comparing the height (H5) from the tip of the guide rib 21 to the tip of the peripheral wall 14 in the container body 10 with the height (H6) from the tip of the lid peripheral wall 34 to the tip of the cylindrical portion 36 in the lid body 30, (H6)<(H5) Therefore, when the position of the lid body 30 is not aligned with the container opening 15, that is, when the tip of the peripheral wall 14 and the tip of the lid peripheral wall 34 are in contact with each other, the tip of the cylindrical portion 36 is not in contact with the tip of the guide rib 21 (see FIG. 7).

[0032] [Operation of the embodiment] [When collecting samples] The sample collection container 1 configured as above is used by a user who collects a sample with the lid 30 screwed onto the container body 10. In an unused sample collection container 1, the discharge port 11 of the container body 10 is closed with a container seal 12. The insertion port 31 of the lid 30 is also closed with a lid seal 32. For example, when collecting feces from an industrial animal as a sample, the container body 10 and the lid 30 are separated. Then, a sample is placed into the storage section 16 of the container body 10 from the container opening 15 using a stool collection tool such as a spoon. The sample here is not liquid such as watery stool, but soft or hard stool.

[0033] 5, when a sample is placed in the container body 10, the contained sample 6 is placed inside the guide ribs 21 up to the position of the bottom wall 13. Around the periphery, the contained sample 6 is supported by the tips of the guide ribs 21 and also by the tips of the outer ribs 22. In the storage section 16, the amount of the contained sample 6 decreases from the center to the periphery.

[0034] 6, the lid body 30 is then fastened to the container body 10 so that the cylindrical portion 36 is positioned inside the guide rib 21 of the container body 10. When the lid body 30 is completely fastened to the container body 10, the tip of the lid peripheral wall 34 abuts against the flange 17.

[0035] Here, many stored samples 6 are located inside the guide rib 21. The amount of stored samples 6 located in this area is sufficient to store the stored samples 6 inside the cylindrical portion 36 without any gaps. Therefore, it is possible to store a part of the stored samples 6 as the extrusion sample 7 inside the cylindrical portion 36 without any gaps. In addition, in the process of fastening the lid body 30 to the container body 10, the stored samples 6 are sequentially stored inside the cylindrical portion 36. As the stored samples 6 enter the inside of the cylindrical portion 36, the air inside the cylindrical portion 36 flows out to the outside of the cylindrical portion 36 through the slit 38. In addition, the surplus sample that cannot be stored inside the cylindrical portion 36 inside the guide rib 21 is pushed by the tip of the cylindrical portion 36 and moves to the base end side (lid wall 33 side) of the cylindrical portion 36 through the gap 39. As a result, the extrusion sample 7, which is a part of the stored samples, can be stored inside the cylindrical portion 36 without any gaps. The sample collection container 1 is stored in the state shown in FIG. 6 and is transported to a testing facility.

[0036] Here, the sample is generally opaque in many cases. When the sample is contained in the container body 10, it is difficult to visually confirm the positions of the guide rib 21 and the outer rib 22. As shown in FIG. 7, this state is a state in which the position of the lid body 30 is not aligned with the container opening 15, and the tip of the peripheral wall 14 and the tip of the lid peripheral wall 34 are in contact with each other. In such a case, the tip of the cylindrical portion 36 is not in contact with the tip of the guide rib 21. Therefore, it is possible to prevent an erroneous operation of forcibly closing the container opening 15 with the lid body 30 in a state in which the positions of the cylindrical portion 36 and the guide rib 21 are misaligned.

[0037] If (H6)>(H5), the tip of the cylindrical portion 36 will hit the tip of the guide rib 21. In this case, if the lid 30 is forcibly pushed into the container body 10, the tip of the cylindrical portion 36 will be strongly pressed by the tip of the guide rib 21. As a result, there is a risk that at least one of the tip of the cylindrical portion 36 and the tip of the guide rib 21 will be damaged. In this embodiment, the occurrence of such an event can be suppressed.

[0038] [During inspection] As shown in FIG. 8, an extrusion member 2 is prepared for an inspection agency or the like. The extrusion member 2 includes a shaft portion 3 and a flange 4. One end 3a of the shaft portion 3 is an insertion end into the insertion port 31 and is an extrusion end for extruding the extrusion sample 7 inside the cylindrical portion 36. One end 3a of the shaft portion 3 has a cone shape so that the container seal 12 can be cleaved. The other end of the shaft portion 3 is provided with a flange 4. The diameter of the shaft portion 3 is a diameter that can be inserted into the inside of the cylindrical portion 36, and is, for example, approximately the same as the inner diameter (D2) of the cylindrical portion 36. In addition, the length from the base end to the tip of the shaft portion 3 is the length inserted from the insertion port 31 and protruding from the discharge port 11. For example, the length of the shaft portion 3 is longer than the height (H7) from the outer surface of the bottom wall 13 to the outer surface of the cover wall 33 when the cover body 30 is fastened to the container body 10 (see FIG. 9).

[0039] The flange 4 has an outer diameter larger than the diameter of the insertion port 31. It is a stopper when the shaft portion 3 is inserted into the cylindrical portion 36 through the insertion port 31. The flange 4 abuts against the upper surface of the cover wall 33 when the insertion end of the shaft portion 3 protrudes from the discharge port 11. Such a push-out member 2 is a single item when the pushing operation is performed manually. When used in an inspection device, multiple push-out members 2 are arranged in the inspection device. Correspondingly, multiple sample collecting containers 1 are supported on a support stand of the inspection device. The push-out members 2 are simultaneously inserted into the insertion ports 31 of the multiple sample collecting containers 1 supported on the support stand.

[0040] As shown in Fig. 9, when an inspection is performed, first, the container seal 12 closing the discharge port 11 is peeled off from the bottom wall 13. Then, the push-out member 2 is pressed against the lid seal 32 from one end 3a and cleaved open. Then, the shaft portion 3 advances into the inside of the cylindrical portion 36. Then, the extrusion sample 7 inside the cylindrical portion 36 is discharged from the discharge port 11 into a container such as an analyzer.

[0041] [Effects of the embodiment] (1-1) After the contained sample 6 is contained in the container body 10, the container opening 15 of the container body 10 is closed with the lid 30. At this time, an extruded sample 7, which is a part of the contained sample 6, is contained inside the cylindrical portion 36. When removing the contained sample 6, the push-out member 2 is inserted into the cylindrical portion 36 through the insertion port 31. Then, the extruded sample 7 inside the cylindrical portion 36 is discharged from the discharge port 11 by the push-out member 2. Therefore, the extruded sample 7 is quantified by being contained in the cylindrical portion 36.

[0042] (1-2) When the container opening 15 is closed with the lid 30 , the cylindrical portion 36 is guided by the guide rib 21 , so that the tip of the cylindrical portion 36 can be smoothly brought close to the discharge port 11 .

[0043] (1-3) Since the outer rib 22 is taller than the guide rib 21, the contained sample 6 is naturally drawn to the inside of the guide rib 21, and the amount of contained sample 6 increases in that area. Therefore, the extrusion sample 7 contained in the cylindrical portion 36 during the process of closing the container opening 15 with the lid 30 is contained without any gaps inside the cylindrical portion 36. This allows a quantified amount of the extrusion sample to be discharged from the discharge port 11.

[0044] (1-4) When a portion of the contained sample 6 is separated from the other contained samples 6 and contained as the extruded sample 7 in the cylindrical portion 36 during the process of closing the container opening 15 with the lid 30, the slit 38 allows the air inside the cylindrical portion 36 to flow to the outside. Therefore, the extruded sample 7 is contained without any gaps inside the cylindrical portion 36. This allows a quantified amount of the extruded sample 7 to be discharged from the discharge port 11.

[0045] (1-5) When the position of the lid body 30 is not aligned with the container opening 15, the tip of the peripheral wall 14 and the tip of the lid peripheral wall 34 come into contact with each other, so that the tip of the cylindrical portion 36 is not in contact with the tip of the guide rib 21. Therefore, it is possible to prevent an erroneous operation of forcibly closing the container opening 15 with the lid body 30 when the positions of the cylindrical portion 36 and the guide rib 21 are misaligned.

[0046] (1-6) The cylindrical portion 36 includes a lid-side guide portion 36a, and the guide rib 21 includes a container-side guide portion 21a. Therefore, when the container opening 15 is closed with the lid 30, the cylindrical portion 36 can easily enter the inside of the guide rib 21.

[0047] (1-7) In the specimen-sampling container 1, the container opening 15 can be securely closed by screwing the cover 30 onto the container body 10. This provides the specimen-sampling container 1 with excellent airtightness.

[0048] [Modifications] The specimen collection container 1 may be modified as follows: In addition to the above embodiment, the specimen collection container 1 may be modified as follows, or may be a combination of at least two of the modified examples that are not mutually contradictory.

[0049] When the lid body 30 is screwed onto the container body 10 by a screw action, the number of rotations of the lid body 30 relative to the container body 10 may be three or more rotations. Furthermore, the lid body 30 does not have to be fastened to the container body 10 by a screw action. For example, the container body 10 omits the threaded portion 18 from the portion above the flange 17. The threaded shape 35 is also omitted from the inner surface of the lid peripheral wall 34. The lid body 30 may be press-fitted into the cylindrical portion above the flange 17.

[0050] As long as the tip of the cylindrical portion 36 can smoothly enter inside the guide rib 21, either the container side guide portion 21a or the lid side guide portion 36a may be omitted. The number of slits 38 formed in the cylindrical portion 36 from the tip (lower end) to the base (upper end) is not limited to two, but may be one, or may be three or more equally spaced in the circumferential direction. For example, four slits 38 may be provided to form a cross shape.

[0051] When a through-hole is provided in the cylindrical portion 36, the through-hole may have a shape other than the slit 38. For example, the through-hole may be a polygonal through-hole such as a circle, a triangle, or a rectangle.

[0052] The height (H4) of the cylindrical portion does not have to be a height such that the tip of the cylindrical portion 36 is spaced apart from the tip of the guide rib 21 when the tip of the lid peripheral wall 34 abuts against the tip of the peripheral wall 14.

[0053] The outer rib 22 may be omitted from the container body 10. For example, when the outer diameter of the container body 10 is small, the distance between the guide rib 21 and the peripheral wall 14 becomes small, so that the outer rib 22 can be omitted.

[0054] If the outer diameter of the container body 10 is smaller, the guide rib 21 may be omitted. This is because if the diameter of the container body 10 is small, a part of the contained sample 6 can be contained in the extrusion sample 7 inside the cylindrical portion 36.

[0055] The shape of the insertion opening 31 is not limited to a circle, and may be an ellipse or a polygon such as a triangle or a rectangle. The shape of the discharge opening 11 is also not limited to a circle, and may be an ellipse or a polygon such as a triangle or a rectangle.

[0056] The water-repellent coating on the surface of the container seal 12 facing the inside of the container body 10 may be omitted. The container seal 12 may be made of a pierce film rather than a peel film. The lid seal 32 may be made of a peel film rather than a pierce film. If the container seal 12 is a pierce film, the pierce film is torn by the compression force of the extruded sample.

[0057] The cylindrical portion 36 may be provided on the bottom wall 13 of the container body 10, rather than on the lid wall 33 of the lid body 30. In this case, the guide rib 21 functions as the cylindrical portion. The inner diameter of the guide rib 21 is set to correspond to the diameter of the shaft portion 3 of the extrusion member 2, like the inner diameter of the cylindrical portion 36.

[0058] The sample may be chicken feces, in addition to feces from cows and pigs. In other words, the sample is not limited to feces from industrial animals. In the case of feces from industrial animals, the sample may be collected at a place where feces from many industrial animals are collected. Furthermore, the sample may be feces and urine from pets such as dogs and cats, or human feces. Furthermore, the sample may be sludge that has settled on the bottom of a river, lake, or ocean, or excrement that has settled on the bottom of a pond or a breeding tank for cultivating farmed fish.
